Does the bible say that faith is the belief in something more than what you know?

Hebrew 11:1 (NLT)

"Faith is the confidence that what we hope for will actually happen; it gives us assurance about things we cannot see."

KJV Hebrews 11:1 "Now, faith is the substance of things hoped for and the evidence of things unseen..."

Do you believe a chair can support a person in a sitting position? One can conceivably not believe so and therefore never sit in a chair or the opposite, believe and try the chair out...

To sit on a chair never sat in before, without checking it by placing one's hand or foot or hesitantly beginning to squat, but, rather sit as though in full confidence the chair will not fall out from underneath...this is faith in what one hopes for (the chair will hold) and evidence of that unseen (that specific chair supporting another of similar weight and shape).

Faith goes beyond belief because it drives action through purpose often correlated to belief.
